Why do I need to change MATLAB path in order to read the files?

I am reading 50 files from a folder as follows:

list_of_files=dir(fullfile('/home/user/Desktop/MTP/schemes/o33smnpimp/data/', '*.dat'));

My problem is until & unless I have same exact folder opened as path in MATLAB path (one above the path window) this command won't work. What is the reason behind this? Actually there are multiple schemes and every time I need to run a particular scheme, I have to go to the data folder of that particular scheme. How can it be solved?

The issue is that you can get the list of files using the full path like you have but you ALSO need to specify the full path when you use it. For example, try changing your code to:

baseDir = '/home/user/Desktop/MTP/schemes/o33smnpimp/data/'; % <--- will use this twice
list_of_files=dir(fullfile(baseDir, '*.dat'));

for ind = 1:length(list_of_files)
    myFilenameFull = fullfile(baseDir, list_of_files(ind).name);  % <---- must use fullfile here too!
    D1 = getData(myFilenameFull, 'stuff');
end
